[ Gearbest Technology News]Network equipment manufacturer Ciena is developing next-generation3.2Tbps level coherent optical communication technologythe transmission capacity is doubled compared to the currently commercialized 1.6Tbps products. The company announced at the “AI Data Center Optical Communication and Internet Technology Conference” held in Seoul on June 24 that it had completed a transmission demonstration of 3.2Tbps coherent optical communication using a 2-kilometer interval.
1. Technical breakthrough: 225GBaud optical signal verifies 3.2T commercial feasibility
This demonstration uses225GBaud optical signaland450Gbps PAM4 technologyjointly completed by Ciena, McGill University, Hyperlight and Keysight in Canada. Kim Sung-jun, Vice President of Ciena Korea, said: “Currently, 1.6T products have been commercialized and 3.2T technology has been demonstrated. It is expected thatWithin 1 to 2 yearsIt will be launched as a commercial product. “Ciena is the first company in the world to invent coherent optical communication technology. Since launching the first WaveLogic platform in 2005, it has developed the sixth-generation product WaveLogic 6, which supports up to 1.6Tbps transmission on a single wavelength.
2. AI computing power expansion driver: leap from 800G to 3.2T
3.2T technology aims atAI data center interconnectionneed. As the scale of AI computing continues to expand, it is difficult for a single data center to overcome power and space bottlenecks. Connecting GPU clusters in multiple regions and using them as a unified infrastructure “Scale Across” architectureis gradually becoming mainstream.
Nvidia is also promoting the continuous upgrade of transmission capacity – the Blackwell generation is an 800Gbps connection, the next generation Vera Rubin will be increased to 1.6Tbps, and subsequentFeynman platformIt is planned to adopt3.2Tbps level network. Ciena is targeting this trend and extending its long-distance coherent optical communication technology to AI data center interconnection scenarios.
3. Strategic layout: Expand related pluggable product lines and deepen the DCI market
Ciena is expanding its coherent pluggable product line with this technology direction as the core, while also expanding data center interconnection application scenarios. Last year, Ciena also acquired Nubis to strengthen the layout of the Scale-Up and Scale-Out markets within the data center – Ciena focuses on the long-distance and DCI fields, while Nubis is responsible for optical connection solutions within the data center, forming a complete product matrix for internal and external collaboration.
